The team measured properties such as the maximum tensile strength and Young's modulus of a series of material tapes pristine Kevlar, Kevlar-epoxy composite, and five Kevlar-MWCNT-epoxy composites, which each contained a different weight-percentage (wt %) of nanotubes.
Kevlar is the registered trademark for a para-aramid synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, this high-strength material was first commercially used in the early 1970s as a replacement for steel in racing tires.

DragonPlate has been CNC machining carbon fiber parts for our customers for 8 years. Parts have included radar components for the Department of Defense, racing parts for Ducati super bikes, structural components for UAVs and reinforcements for stringed musical instruments.
DuPont’s Kevlar is a fiber, not a composite. Thus, the question is: “What composites have similar characteristics to a Kevlar composite?” This again is something of an issue, since “composite” automatically means more than one material. A Kevlar belted tire is a composite, as is concrete with chopped Kevlar fiber in the mix.
Kevlar is often combined with other materials, to produce textiles with enhanced properties, such as fire resistant clothing for the Fire Services. Kevlar is used in some quality walking boots because it is waterproof (when combined with other materials as a composite) but also breathable, ensuring comfort.
Kevlar Properties DuPont Kevlar is an organic fiber in the aromatic polyamide family. The unique properties and distinct chemical composition of wholly aromatic polyamides (aramids) distinguish them - and especially Kevlar - from other commercial, man-made fibers.
Some non brittle material distorts before breaking, but Kevlar, Carbon Fiber and E glass are brittle and fail with almost no distortion. Tensile Strength is measured in Force per unit area: Pa or Pascals. Ultimate tensile strength (UTS) or ultimate strength are terms also used. Stress is the force, strain is the deflection due to stress.

Composite Machining. Mica-Tron Products Corp. has been machining composites since it opened its doors in 1959. Over the decades, we have had the opportunity to machine a wide variety of grades of commercially available composite materials, including special grades which composite manufacturers develop on a "proprietary" basis, specifically for our customers' applications.
The material of these reeds is a composite of aerospace materials designed to duplicate the way nature constructs cane reed. Very stiff but sound absorbing Kevlar fibers are suspended in a lightweight resin formulation.

Kevlar / Aramid Incredible Strength Lightweight Available in Quantities small to large Kevlar 49 material is rated primarily for industrial applications including sporting goods, boats and as reinforcements in other composite structures.
Dry machining of carbon is a lot more difficult because of the heat and dust. You'll have to wait for another poster or do some research on machining Kevlar. I've cut it a few times and had success, but I don't want to give any recommendations because I really don't know what proper techniques are.
The addition of nanotubes to the composite was shown to improve the mechanical properties in all cases, but the best-performing composite contained 0.3 wt % MWCNTs its maximum tensile strength was ~81% higher than the Kevlar-epoxy composite.
KEVLAR fabrics can be used with, or as a great alternative to carbon fiber or fiberglass. Composites-grade KEVLAR is lightweight, impact resistant, abrasion resistant, heat resistant, and has great strength properties for the most demanding applications. Fibre Glast only carries KEVLAR 49 fabrics.
